    There's a similar magic we've seen countless time with XO: you have a bug that nobody reports for years and suddenly it pops from various sources (or with many details so it's easy to spot), you think it's recently introduced, you check your diff and then after hours you realize it's there since a while

    It's not meant to be used like that. If you are behind a NAT, the right approach is to have your XOA behind the NAT and inside the same network than the hosts. That's because hosts will always use and return their internal IPs to connect to some resources (stats, consoles etc.). XOA deals with that easily as being the "main control point" for all hosts behind your NAT (or a XO proxy if you prefer).

    @florent said in Problems import vm Vmware to Xcp-ng from import Vmware and OVA: @olivluca skip ssl check in the import form I already did that. In fact it connects and I can get a list of VMs to import.

    From the xe help host-shutdown and xe help host-disable "If no parameters to select hosts are given, the operation will be performed on all hosts." I have a single host pool, so I can't test.

    I have no clue, I usually back it up with XO, its the one called "XO config & pool metadata backup" and only had to restore it once.

    Resolved. Patched the rest of the hosts. Restarted all the toolstacks for good measure. I can move the master role now, and deploy new VMs.

    Actually Alma Linux does have a variant for v2 CPUs so they can run 10.0. Just look for x86_64 v2 on the downloads page.

    log_fs_usage / /var/log directory on pool master filling up constantly

    Another thing that I noticed: despite enabling remote syslog (to graylog) for all XCP-ng hosts in the pool /var/log gets filled up to 100%. Adding remote syslog seem to not change usage of /var/log at all. Official XCP-ng documentation states otherwise here: https://docs.xcp-ng.org/installation/install-xcp-ng/#installation-on-usb-drives The linked part of the documentation indicates that configuring remote syslog can be a possible solution for /var/log space constraints which seems to be not the case. I feel like logging could use some investigation by Vates in general.

    Hi Forza, Have you finished migrating the workloads? If you are still looking for an easy migration solution, you can try Vinchin Backup & Recovery. It will replace the driver during migration intelligently.

    @olivierlambert Thank you for the reply. There was a thread on here about the iso not being mounted properly and I commented about having power off the vm and back and it will load the iso. This is specifically true with the 0.4.0 for linux. Image pulled from the XO Hub will not mount the ios if the vm is powered on. There is Yellow Explanation mark next to it. Power off vm and power on vm iso is ok. Reboot vm does not let the ios to work.

    @AtaxyaNetwork @Pilow @bvitnik Ok, knowing that the p2 partition was likely an old backup was exactly the breadcrumb that I needed. I confirmed via chroot and xsconsole that p2 was xcp-ng v8.2.1, and that p1 was v8.3. Then I was able to check the initrd files there. Namely I needed to see the updated dates and the kernel version. Thankfully, I saw initrd files on the backup that were the correct kernel and hadn't been disturbed. I then just cloned the initrd files from the backup partition to the p1 partition and BOOM. We booted right up. Much appreciated for the assistance, everyone. I'll still need to figure out why my disks are disconnecting, but that will be another post for another day.

    @Pilow Yes, we monitor observability metrics for guest OSes via other means but being able to see this info via the Xen Orchestra web UI along with the other metrics in the Stats tab definitely has is benefits, especially when performing initial troublehshooting or when dealing with groups in our org that only have access to the XO interface and not the other metrics dashboards. Don't get me wrong, I definitely appreciate all of the work that you are all doing to get these tools working and can't wait to start using them in production. I just need to make sure that they work as expected.

    @zpvS9 said in Error installing windows PV drivers 9.0.9137: I have this error too installing the new PV driver, after uninstalling Citrix driver, reboot, execute XenClean, reboot again, it said that an unsupported device is still present. I must uninstall the device by showing hidden device in Device manager and the Windows PV driver now install. So adding this step in XenClean would be appreciated. encountered the same problem with hidden base system that i needed manually uninstall to get the tools to work.

    @rustylh We really need more information to even begin. What version of XCP-ng are you using? What hardware are you using to run XCP-ng? What is the underlying storage where the VM resides on? What OS is the VM running? How are you taking snapshots, XO? How old was the snapshot? Were the guest utilities installed into the VM? You do know snapshots are not backups, right?

    So first, it's not an XO issue, which helps to diagnose it. Then, it might be a subtle XCP-ng bug indeed.

    said in Unable to enable High Availability - INTERNAL_ERROR(Not_found): said in Unable to enable High Availability - INTERNAL_ERROR(Not_found): @psafont Would designating a new pool master do the same thing? I ran the above command and its had no effect Well, I tried changing the pool master and when VMHost11 was the master I was able to enable HA. Switching back to VMHost13 as the master now so will see how that goes Everything is working as expected/hoped. So for anyone reading through this and wants a TL;DR Issue was related to the pool master setting, changing the pool master to a different host and then back to the original fixed the incorrect settings allowing HA to be enabled
